Embodiment Construction
[0027] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0028] Taking the two-compartment rotary air preheater as an example, the main structure of the rotary air preheater of the present invention is as follows: figure 1shown. The rotor 1 installed in the shell 2 rotates slowly around the rotating shaft 3, and the rotor 1 is divided into several fan-shaped compartments by several compartment partitions 5 in the radial direction, generally 24 or 36 or 48 compartments, above and below the shell 2 There are two pairs of fan-shaped plates 6 (four in total) in the radial direction, two arc-shaped plates 7 in the axial direction of the casing 2, and radial seals 8 are installed radially at the hot and cold ends of each compartment partition plate 5 of the rotor 1 The radial corrugated elastic seal 21 is installed on the top, and the axial corrugated elastic seal 22 is installed on the position where the axial...
